On one of the most lackluster weeknight showings by the Big Four in recent memory, no broadcast network could claim more than 5% of the available young-adult audience on Tuesday. NBC’s new reality combo, Fox’s comedy block and CBS’ repeat crime dramas all grabbed a share of the demo lead.

The start of daylight savings time continues to be largely responsible for lighter viewing levels, especially early in the evening. Nielsen said Wednesday that only 30% of adults 18-49 were watching television in Tuesday’s 8 p.m. half-hour, a decline of 10.7% week to week. And the falloff was even steeper among the 18-24 crowd, where just 20.7% of that age group was in front of their television set early in primetime, down 13.4% week to week.

According to preliminary national estimates from Nielsen, NBC’s premiere of ”Fashion Star” settled for a 1.6 rating/4 share in adults 18-49 and 4.6 million viewers overall , and yet neither CBS nor ABC could do better among the 18-49 crowd in the 9:30 to 11 p.m. window. The new reality contest pretty much held its audience from start to finish, airing after a 90-minute edition ”The Biggest Loser” (2.0/6 in 18-49, 6.3 million viewers overall), which managed to match its delivery of last week.

”Fashion Star” should get a lift in a few weeks when it begins to air following the new results show for singing competition hit ”The Voice.”

Fox’s second week of a four-comedy block showed declines, with anchors ”Raising Hope” (1.8/6 in 18-49, 4.3 million viewers overall) and ”New Girl” (2.7/7 in 18-49, 5.7 million viewers overall) both down three ticks; still, ”New Girl” was the night’s No. 1 show in 18-49. Also down some were ”I Hate My Teenage Daughter” at 8:30 (1.3/4 in 18-49, 3.5 million viewers overall) and ”Breaking In” at 9:30 (1.5/4 in 18-49, 3.5 million viewers overall). From 8 to 10 p.m., Fox ran third in 18-49 but first in 18-34 (1.6/6).

CBS won the night outright in adults 25-54 (2.6/6) and total viewers with encores of ”NCIS” (2.1/7 in 18-49, 12.7 million viewers overall), ”NCIS: Los Angeles” (1.9/5 in 18-49, 11.3 million viewers overall) and ”Unforgettable” (1.3/4 in 18-49, 7.3 million viewers overall). ”NCIS” was the No. 2 program of the night in 18-49, and No. 1 in both 25-54 and total viewers.

ABC, edged out on the night in 18-49 by Univision, opened with a repeat ”Last Man Standing” (1.3/4 in 18-49, 5.4 million viewers overall) and an original ”Cougar Town” (1.4/4 in 18-49, 4.4 million viewers overall), with the latter down a tick from last week but moving narrowly ahead of Fox’s ”Teenage Daughter.” The comedies were followed by the penultimate week of ”The River” (1.3/4 in 18-49, 4.1 million viewers overall), which hit a low, and ”Body of Proof” (1.4/4 in 18-49, 7.3 million viewers overall), which was competitive with CBS and NBC in 18-49 for the 10 o’clock hour.

CW aired original episodes of ”90210” (0.6/2 in 18-49, 1.2 million viewers overall) and ”Ringer” (0.4/1 in 18-49, 1.1 million viewers overall).
